The highest incidence of invasive candidiasis infection (ICI) occurs in low birth weight infant with an estimated incidence of 4% and of 15% in extremely low birth weight infant. Low birth weight is an important risk factor. The other main risk factors associated with invasive candidiasis are the use of multiple antibiotics and central venous catheters, immunosuppression, parenteral nutrition, fungal colonization, and necrotizing enterocolitis. In this population, ICI cause high mortality, lead to significant neurodevelopmental impairment, and result in increate length of hospitalization and cost. [1] Originality of the study is the use of probiotics combination Alkem Batch PWS3002C comprising Bifidobacterium infantis, Lactobacillus acidophilus, Bifidobacterium longum, and Bifidum lactis. These preparations are considered more effective than single probiotic strain, characterized instead by a single bacterial strain. In fact, a recent study showed that the use of a multistrain probiotics have an action of greater efficacy. [2] Important focal point is gastrointestinal symptoms. Another interesting result of this study is that the control group presented a higher percentage of gastrointestinal symptoms than did the probiotic group, which showed an increased food tolerance, shortening the period of parenteral nutrition probably due to its changes in intestinal flora, improvement in mucosal barrier and anti-infiammatory properties. Reduction of stool fungal colonization is an important principal outcome parameter in the probiotics group by reduced invasive fungal sepsis is an important outcome parameter in the probiotics group because reduced invasive fungal sepsis 55.4% in probiotics group versus 75% in the control group. [3] Also the number of days to full enteral feeds and duration of hospitalization was less in probiotic group. Candida albicans is the most commonly isolated species, although C. parapsilosis. These species are commonly isolated in invasive candidiasis, while C. glabrata and C. krusei are isolated only in 3% of ICI. The published data show that fluconazolo use since birth is highly effective in preventing both colonization and infection in preterm neonates. This can lead to a high prevalence of azole-resistant Candida species. [4] In this study 35 (7%) newborns of control group presented C. glabrata infection, while the probiotics group presented only C. albicans. Loss of gut commensals, such as Bifidobacteria and Lactobacilli, due to the difficulties in oral feeding, translates into an increased susceptibility to pathogenic gut colonization. Probiotics are increasingly being used for their beneficial properties, considered to be particularly useful in reducing some symptoms related to gastrointestinal disorders. [5] In particular, preparations of a multistrain, consisting of different bacterial strains but belonging to the same species or anyway similar species are considered more effective than single probiotic strain. Evidence regarding the potential beneficial effects of probiotics supplementation in preterm infants is encouraging. Further studies to assess clinically relevant outcomes are needed.
